The toilet bowl body 2 and the pair of peripheral wall members 3 are in the state of molded products before firing, respectively, with the joint surfaces 43A, 43B, 43C, and 43D on the side of the toilet bowl body 2 and the joint surfaces 3C, 3D, 3E, and 3F of the peripheral wall members 3. It is joined by applying glue for joining between them.

Next, a method for manufacturing the flush toilet 1 according to this embodiment will be described.
First, a method for manufacturing the toilet body 2 will be described. As shown in FIG. 8, the toilet body 2 is obtained by sintering a molded product formed by bonding an upper body 70 and a lower body 80 together. The upper formation 70 and the lower formation 80 are each formed by casting slurry. The fired body of this upper formation 70 forms the upper member. The fired body of the lower formation 80 forms the lower member. Upper formation 70 and lower formation 80 have mating surfaces 71 and 81, respectively. The joint surfaces 71 and 81 are respectively formed of a downward surface and an upward surface substantially parallel to the front-rear direction and the left-right direction. The upper forming body 70 and the lower forming body 80 are joined by applying a slurry for joining between the respective joint surfaces 71 and 81 .

As shown in FIG. 8 , the upper forming body 70 includes a portion of the upper end side of the toilet bowl portion 10 of the toilet body 2 , the upper surface portion 30 , a portion of the rear upper end side of the outer wall portion 40 , and the upper end side of the rear wall portion 50 . and a part of the upper end side of the water supply part 60, respectively. The lower forming body 80 forms the portion of the toilet bowl portion 10, the trap portion 20, the outer wall portion 40, the rear wall portion 50, and the water supply portion 60 of the toilet bowl body 2, excluding the portion formed by the upper forming body 70. are doing. The upper forming body 70 and the lower forming body 80 are joined together at joint surfaces 71 and 81 formed on the respective parts. That is, since the upper formation body 70 and the lower formation body 80 are separately formed, the configuration of the complicated internal flow path and the like is divided into upper and lower parts.

In the case of the present embodiment, the bonding member 4 made of ceramic is formed between the bonding surface 71 and the bonding surface 81 by firing mud for bonding. That is, the upper body 70 and the lower body 80 before firing are fired together with the mud for bonding between the bonding surfaces 71 and 81 to form the toilet body 2 integrally bonded by the bonding member 4. Form.

The manufacturing method of the peripheral wall member 3 is the same as that of the toilet body 2 . That is, the peripheral wall member 3 is obtained by firing a molded product 103 formed by casting slurry. In the present embodiment, the peripheral wall member 3 is joined to the toilet body 2 in the molded product state in the molded product 103 state (see FIG. 9).

That is, in the manufacturing method of the flush toilet bowl 1 of the present embodiment, first, the upper formation 70 and the lower formation 80 formed by casting slurry are obtained. Then, as shown in FIG. 8, the joining surfaces 71 and 81 of the upper and lower forming bodies 70 and 80 are coated with mud for joining and joined. Thereby, the molded article 102 of the toilet body 2 before baking is obtained.

A molding 103 of the peripheral wall member 3 obtained by casting slurry is joined to a molding 102 of the toilet body 2 . At this time, as shown in FIG. 9, the molded product 102 of the toilet bowl body 2 is turned upside down with a backing plate or the like applied to the upper and lower surfaces. As a result, the upper surface portion 30 of the molded product 102 is grounded and stabilized, and the outer wall portion 40 is disposed so as to widen downward, thereby facilitating the joining operation.

Mud for bonding is applied to the bonding surfaces 43A, 43B, 43C, and 43D on the toilet body 2 side. Of the joint surfaces 43A, 43B, 43C, and 43D of the toilet body 2 with the peripheral wall member 3, the joint surface 43A is formed on the upper formation 70, and the joint surfaces 43B, 43C, and 43D are formed on the lower formation 80. ing. Then, the joint surfaces 3C, 3D, 3E, and 3F on the side of the peripheral wall member 3 are aligned and joined to the joint surfaces 43A, 43B, 43C, and 43D on the toilet body 2 side. That is, the peripheral wall member 3 is joined to each of the upper formation body 70 as the upper member and the lower formation body 80 as the lower member. Then, the flush toilet bowl 1 is obtained by applying glaze and firing. In the flush toilet bowl 1 thus obtained, the pottery body 2 and the pottery peripheral wall member 3 are integrally joined by the pottery joining member 4, and good design is obtained. By joining the toilet bowl body 2 and the peripheral wall member 3 in the state of the molded products 102 and 103 before firing, they are firmly and integrally joined by the joining member 4 formed by firing the slurry for joining, and the joints are formed. It is possible to obtain a flush toilet bowl 1 having an outer peripheral surface 1A that is inconspicuous.

As described above, the flush toilet 1 of Embodiment 1 is a flush toilet in which the outer peripheral surface 1A is formed continuously from the front surface to the left and right side surfaces, and has the outer wall portion 40 that forms the outer peripheral surface 1A. A toilet bowl body 2 made of ceramics and a peripheral wall member 3 made of ceramics joined to an outer wall part 40 to form a part of an outer peripheral surface 1A are provided.

Thus, the flush toilet bowl 1 can form the outer peripheral surface 1A with ceramics. Therefore, it is possible to secure a good design compared to the conventional case where a part of the outer peripheral surface is made of resin. Since the peripheral wall member 3 can be manufactured separately from the toilet body 2, the degree of freedom in design can be improved.

The flush toilet bowl 1 of Embodiment 1 includes a pottery joining member 4 that joins a toilet body 2 and a peripheral wall member 3 . As a result, the entire outer peripheral surface 1A is made of ceramic, and the design can be improved.

In the flush toilet bowl 1 of Embodiment 1, the peripheral wall member 3 forms a side surface on the rear side of the outer peripheral surface 1A. As a result, compared to the case where the joining portion with the outer wall portion 40 appears on the front surface of the outer peripheral surface 1A, it is possible to improve the design.

In the flush toilet bowl 1 of Embodiment 1, the toilet bowl body 2 is joined to the fired body of the lower forming body 80 as the lower member having the outer wall portion 40, and the upper portion of the lower member to form the upper surface of the flush toilet bowl 1. and a sintered body of the upper forming body 70 as an upper member to be formed. Thus, the flush toilet bowl 1 is composed of the toilet body 2 and the peripheral wall member 3 which are formed of the fired body of the upper forming body 70 and the fired body of the lower forming body 80 . Therefore, it is possible to easily form complicated internal flow paths such as a trap portion and a water supply portion. As a result, the degree of freedom in design can be further improved.

In the flush toilet bowl 1 of Embodiment 1, the toilet bowl body 2 having the fired body of the upper forming body 70 as the upper member has a flat surface 30A and a curved surface 30B having an arcuate cross section that is continuous with the outer peripheral edge of the flat surface 30A. The peripheral wall member 3 is joined to the fired body of the upper forming body 70 in such a manner that the upper end of the surface 3A continues to the lower end of the curved surface 30B. Therefore, it is possible to make the joining portion between the curved surface 30B and the surface 3A of the peripheral wall member 3 inconspicuous, thereby improving the design.
